GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 622,744, dated April 11, 1899. Application filed January 13,1896. Renewed January 12, 1399-$81i N0- 70210011 (No 11105161) To Cl/ZZ whom it may concern:

Be it known that 1, PAUL A. N. WINAND, a subject of the King of Belgium,and a resident of Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented certain new and useful Improvements inGas-Generators, of which the following is a specification.

In my improved organization I provide an annular reservoir for the fuellocated at the top of a generator and feed the fuel from the reservoirto the generator ciroumferentially around a centrally-arrangedwater-cooled bell, dome, or chamber, through which the products ofcombustion or gas is taken off. The effect of so feeding agas-generator, which, however, is not new, is that the supplied fuelforms a bed which slopes naturally from the periphery of the column offuel downwardly toward the center. This manner of feeding and theconsequent arrangement of the fuel within the generator induces theblast introduced at the bottom to pass up centrally through the columnoffuel to a greater extent than it will pass along or in proximity to theinterior walls of the generator. The production of clinkers and theformation of channels or passages in the body of the fuel havea tendencyto occur at or adjacent to the walls of the generator, and in myorganization since the blast passes through the column of fuel centrallythese objectionable features are to a very considerable extent avoided.

The generator fuel-reservoirmay be closed by the ordinary cap or topplate of the generator, in which feed-openings at suitable intervals andprovided with proper covers may be formed.

Another feature of my invention is a special I organization involvingthe attachment and mounting of the outlet-pipe for gas or products ofcombustion from the generator centrally, but in such manner as to permitof its ready detachmontand removal to afford access to the centralsloping body of fuel beneath the bell or dome.

My invention also includes certain improvements in the grate involving acentral sta tionary blast-inlet and a grate having circularly-rockingmovement for stirring or agitating the whole bed of fuel and forcing outthe ashes at the base thereof.

In the accompanying drawings, Figure 1 is a vertical section through agenerator constructed in accordance with my improvements; Fig. 2, a planview thereof; Fig. 3, a horizontal section on the line 8 3 of Fig. 1,and Fig. 4 a detail View showing another form of water-cooled bell orvessel in the top of the generator.

The shell and interior walls of the genera tor may be of any usual andappropriate construction except that the upper faces or edges of theWalls are preferably inclined from the periphery inwardly anddownwardly, as indicated at A. Centrally within the casing of thegenerator I provide a bell or inverted vessel B, which may be suitablysecured to the top plate 0 and is formed with double Walls 01 cl,providing an annular chamber for the circulation of Water, which mayenter at cl and leave at (1 Fig. 4: indicates another style ofwatercooled bell or dome B. In this case the bell is formed with aspiral rib or with annular ribs b running around its exterior. Water issupplied from an adjustable tap b to a trapped pipe 11 Whose lower endpasses through the top plate of the generator and terminates inproximity to the exterior of the bell at the top thereof. The supply ofwater will not be such as to impair the proper action of the generator,and its flow will not be unduly impeded by the solid fuel lying againstthe exterior face of the generator.

The water-cooling of the bell enables me to dispense .With the use offire-brick or other refractory material in its construction and alsotends to reduce the temperature within the bell, which in some casesmakes it necessary to further cool the gas by the use of a Water sealand scrubber. Between the exterior face of the bell B and the walls andtop plate of the generator an annular fuel-= reservoir E is thus formed,and the sloping tops A of the walls and the annular exterior of the bellB direct the fuel therein to the outlet F between the edge of the belland the sloping face of the wall. The fuel is there= fore fedcircumferentially to the generator and will tend to arrange itself inthe general manner or condition indicated in the drawings. The top plateis formed with fuel-feeding apertures (1, provided with removablecovers, and from time to time the reservoir may be filled. The usualblast introduced centrally at the base of the column of fuel will find amore ready path through the central portion of the fuel, and the volumepassing through the fuel will gradually decrease from the center towardthe walls of the generator. I have found by practical use that in agenerator so constructed the objectionable production of clinkers at thewalls of the generator, and the consequent obstruction to the proper anduniform descent of the column of fuel, does not occur. I have also foundthat the formation of objectionable channels or passages in the fuel,which usually occur adjacent to the walls of the generator and permitthe passage of the blast through the fuel without proper contact with ordistribution through it, is obviated. The top plate 0 is provided with ahub or short flanged pipe-section Gr, communicating with the interior ofthe dome or bell B, and to it the gas offtake or outlet pipe H may bedetachably connected by swinging screw-fastenings h of usualconstruction. The pipe is then extended laterally and formed with a bendor downwardly-extending elbow H, the lower end of which is immersed in awater seal H mounted upon the upper end of the pipe H A frame or spiderI,'secured across or in the mouth of the pipe H has mounted in it aspindle or shaft 1, that passes through a bearing 1 formed in the pipe11, and is supported to its upper end in a block 1 The fastening devicesh may be opened or released and the pipe H swung laterally, as indicatedin Fig. 2, being supported by and turning upon the spindle I, thusaffording access centrally to the bed of fuel in the generator.

At the base of the generator is the usual ash-pit, and in it is mountedthe grate or plate supporting the base of the column of fuel, theconstruction being as follows: An annular flanged ring or frame in issuitably supported at the base of the generator-chamber, and within itis arranged a circularlyrocking plate K, supported loosely upon posts70, seated in sockets in the under side of the plate and carried in theends of arms of a spider frame L, which is supported loosely by acentral post L, seated in a central socket in the under face of thespider.

A horizontal shaft M has hearings in bushings N, located in the Walls orshell of the furnace and provided with handles n. One or both ends ofthe shaft M may be provided with a crank-handle M, by which it may berotated. Two circular cams or eccentrics m, oppositely fixed upon theshaft M, are embraced by the jaws of the bifurcated radial spider-arms LThe revolution of the shaft M will therefore impart to the plate K acircularly-rocking motion that will stir or-agifree discharge of theashes, the ring K may.

be elevated into the position shown by dotted lines. The blastinlet pipe0 passes through a central aperture in the plate K and may be providedwith the usual guard-cap O. The aperture in the plate may besufficiently larger than the exterior diameter of the blastpipe topermit the circularly-rocking motion of the plate or grate K. I prefer,however, to form a curved boss 0 on the blast-pipe, to the curve ofwhich the edge of the plate would conform during the rocking movement.

I claim as my invention-- j 1. In a gas-generator the combination of theoutlet-pipe H, the inverted vessel or bell within the gen erator-chamberand detachably connected with the pipe, a spindle or shaft upon whichthe outlet-pipe may be swung hori= zontally, the pipe H with which theoutletpipe communicates, and awater seal arranged in the joint betweenthe outlet-pipe and the pipe H g 2. The combination of a gas-outletpipe, H,- the pipe, H carrying a water seal, H in which the outer end ofthe pipe H is immersed, the frame, I, the spindle, I, having a bearingin the wall of the pipe, H, whereby'the pipe, H, may be swunghorizontally, and means for detachably connecting the other end of thepipe with the gas-outlet of the generator.

3. The combination with the gas-generator, of an offtake-pipe detachablyconnected at one end with the gas-outlet of the generator, and pivotedat the other end to move about a ver-' tical axis, and a water seal inwhich the end of the pipe works.

4. The combination of the generator-chant her, a stationary,centrally-arranged blast inlet at the bottom of the generator-chamber,and a rocking plate or grate having an aperture through which theblast-inlet extends and about which the grate oscillates as a center.

5. The combination of a rocking plate or grate located at the base ofthe generator= chamber, the loosely-mounted spider upon which the plateis loosely supported, the shaft and its cams workingbetween the jaws ofthe bifurcated arms of the spider, substantially as set forth.

6. In a gas-generator the combination of the rocking plate or gratelocated in the base of the generator-chamber, a stationary blast-i11-let pipe passing centrally through said plate and about which the platerocks as a center, and means for imparting to the plate a rockingmovement.

7. The combination of the rocking plate or xo faces about which theplate rocks, the spider,

a support upon which it rocks, a series of uprights mounted on the armsof the spider, and a loose connection between the upper ends of theuprights and sockets in the plate.

In testimony whereof I have hereunto sub- I5 scribed my name.
